//定义分隔符，用于分割[select]变量
var TheSplit1 = "*"        //一级选项与一级选项之间的分隔符
var TheSplit2 = "|"        //一级选项与二级选项之间的分隔符
var TheSplit3 = "^"        //二级选项与二级选项之间的分隔符
var TheSplit4 = "@"        //选项文本与选项值的分隔符，可以省略[值为选项文本值]

/*
定义[select]框选项变量,这里以省市二级为例
例：一级选项一|二级选项一^二级选项二^二级选项三*一级选项二|*二级选项三|
*香港|*澳门
注:当一级选项没有二级下属时，请在后面加上TheSplit2分隔符，否帽关联将会出错，所以应该注意防止此类错误发生
如果选项文本与选项值不同时，请在选项文本后加上@值格式:[Text@Value]
如:北京@010|东城@0101^西城@0102
